IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 38,828, dated June 9, 1863.

To all whom it may concern:

Be it known that I, G. G. HUNT, of Quincy, in the county of Adams and State of Illinois, have invented a new and Improved Coal and Gas Burning Stove and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical section of my invention, taken in the line '00 m, Fig. 2; Fig. 2, a horizontal section of the same, taken in the line y y, Fig. 1.

Similar letters of reference indicate correspondin g parts in the two figures.

The object of this invention is to obtain a stove which will burn all the inflammable gases, smoke, 850., evolved by imperfect eombustion, thereby economizing in fuel, and at the same time obviating the difficulty hitherto caused by the flnes of the stove becoming clogged or choked up with soot. The invention is more especially designed for the burning of bituminous 'coal, but anthracite coal maybe used and a saving in that also effecte-"l.

To enable those skilled in the art to fully understand and construct my invention,I will proceed to describe it.

A represents the base of the stove, on which the ash-box B is placed, the latter being provided with adrawer, U, and having a firegrate, D, at its upper end.

E represents the fire-pot, which is fitted on the ash-box B and directly over the grate D.

F represents a series of vertical tubes, the lower ends of which communicate with the upper part of the fire-pot E, as shown in Fig. 1. The upper ends of the tubes F communicate with an annular chamber, G, with which the smoke pipe H communicates. The tubes F are simply flues, as also is the chamber G.

I represents a conical chamber, the lower end of which is fitted centrally into the upper part of the fire-pot E and its upper end fitted in the central opening formed by the chamber G. The chamber I is provided with a lid,

J, which may have a register, K, at its center, and to the inner side of the chamber I there are attached a series of tubes, J, which extend from the bottom of I upward nearly to its upper end.

The central opening, in which the upper end of the chamber I is fitted, is provided with a pendent annular flange, a, which projects downward sufficiently far to prevent the upper ends of the tubes J from being choked up with coal, the latter being thrown into the top of I, as presently shown. This is an important feature of the invention, for if the tubes J should become choked or clogged the stove would be rendered comparatively inoperative so far as the gas-burnin g property is concerned.

The upper part of the fire-pot E is of flaring or bell shape, as shown clearly at b in Fig. 1, and the lower end of the chamber I extends down within a short distance of the bottom of the part b, so as to form a narrow throat, c, all or nearly around the fire-pot.

The operation is as follows: A fire is kindied in the fire-pot E, and when fairly under way the chamber I is nearly filled with coal, the damper d in the front of the ash-drawer c is partly closed, and the register or damper K in the lid J is opened in order to admit air into I, which air passes down through tubes J and ming'es with the smoke and gases in the throat 0, these products of combustion, or, rather, of imperfect combustion, being there by ignited and consumed in the upper part of b and in the tubes F.

Itwill be understood that there is no smoke in the upper part of the chamber I, and the lid or cover J may be entirely removed for replenishing I without any danger of smoke issuing therefrom. The narrow throat 0 causes a uniform draft all around the fire-pot E. This fire-pot, it will be seen, is quite shallow, and is supplied with fuel from I. The minglin g of the air with the smoke and gases at the threat 0 causes the same to be thoroughly incorporated with each other, so as to insure perfect combustion of the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The chamber I, provided with the internal air-tubes J, in combination with the firepot E, fines or vertical tubes F, communicating with the annular chamber G and smokepipe H, all arranged to operate as and for the purpose herein set forth.

2. The annular pendent flange a in the central opening .of the annular chamber G, when placed relatively with the upper ends of the tubes J, to operate as and for the purpose herein set forth.
